Specification of Letters Patent.

Application 518a May 16,1905, Serial No; 260,388.

In a, whom it may concern:

Be it known that I, EDWARD MANnoNNn'r, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Devices toPrevent Refilling of Bottles, of which the following is a specification.

This invention relates to an improved means or device to be fixed in theneck of a bottle for the purpose of preventing the bottle being refilledafter it has been emptied of its original contents, and the samecomprises a novel construction and combination of shell or hollow plugadapted to close the passage tlrrough the neck of the bottle, a

ravity-valve controllin the port or o ening inthe bottom of the she I,and means or fixing the shell in the neck of the bottle, all ashereinafter fully described, and pointed out in the claims at the end ofthis specification.

The combination and operation of my said device will be explained withreference to the accompanying drawings, in which- Figure 1 represents mdevice fixed in place in the neck of a bott e, the body of the deviceand the neck of the bottle being shown in section. Fig. 2 is an exteriorView of the device before it is placed in the bottle, showing the lowerportion of the outer wall and also the valve and its seat part1 insection. Fig. 3 is a transverse section ta en diametrically through theshell above the valve and showing the valve closed on its seat. Fig. 4is a transverse section taken through the shell on the line 4 4, Fig. 1.Figs. 3 and 4 are represented on an enlarged scale.

The part A, which I have termed the shell, is made in two arts a ainclosing a chamber as, having su stantially the same dimensionsdiametrically as the neck of the bottle, but sufficiently small to fitclosely into the neck when inserted through the mouth. Above that ortiona which fits into the neck the shell is enlarged diametricall to reducethe chamber a, and on this en ar e end is fixed the cap or top piece aby a ap-joint a. The shoulder b, which is formed by the increase in thediameter of the up or part a over the body a extends over an rests onthe top rim around the mouth of the bottle, and a rubberwasher or otherpacking (indicated at d, Fig. 1) is placed between the two surfaces tomake a tight joint all around the rim.

In the lower end of the shell a", which is of the same diameterthroughout, is a valveseat 0, provided with a flat to )face and ofcircular outline for a valve 0 the flap kind. The valve has a cup-she.ed or hemispherical body f of approximate y the same dimensionsdiametrically as the opening in the bottom of the shell and a fiat rim faround the circumference to project over and make a close joint with thevalve-seat (2 when closed on it. This last-named part is best formed ofa separate rin rovided with an external groove h, into w nch the wall ofthe shell a is forced after the rin is set in place, as seen in Fig. 1and the va vef being attached to the ring by a hinge g the ring isinserted and permanently fixed by crim in the outer shell into thegroove 71.. The mm of the valve and its position when closed on its seatare seen in Fi s. 1 and 2. Its position when the bottle is tipped topour the liquid is indicated by the dotted lines in Fig. 1.

In the enlarged chamber a" above the neck a stationary uard permanentlyfixed to the walls of the chamber rotects the valve from being tamperedwith om the outside.

A protector of some kind is required to revent the valve being reachedand held 0 its seat by introducing a wire or other instrument throughthe mouth of the bottle, and in the present device the means providedfor that purpose is constructed with a view to afford the necessaryrotection without materially afiecting the ca outflow of the liquid.This art is composed of several conical rings m of ifi'erent diametersplaced concentrical y one within another and fixed in that position bymeans of crossrods 1), extending diametrically through the conical ringsat right angles to each other, and from one side to the other of thesurroundin shell to the sides of which the rods are fixed. The conicalrings are so arranged one within the other that the u per ed e of eachring will overlap the lower edge of t e ring lying next within it, andthe space separating each ring and the next is necessari y inclinedoutwardly or toward the side wall of the chamber (1. instead oferpendicularly downward. The efl ect of t 's construction is to reventthe introduction of a wire throu h t e mouth or outlet into thevalve-chain er o while not interfering with or materially reducing thearea of the discharge.

In the top of the cap-piece a an outlet 8 is provided for the dischargeof the li uid, and a spout or neck 1*. surrounds the out et to receive acork w for closing and sealing the bottle. This neck is spun orotherwise formed integrally with the cap-piece to reduce the number ofjoints.

The means for fixing the plug in place should be such that the devicecannot be removed without destroying it or breaking the bottle, and atthe same time it must be readily applied without increasing the expenseor requiring much exercise of Sklll or labor. The fastening means forthis purpose (illustrated in Figs. 1 and 2) is self-acting in itscharacter and consists of spring-catches attached to the inside of theshell a and pro'ecting through apertures in the walls of the s ell, soas to enga e notches or shoulders Z, formed in the wa l of the neck ofthe bottle just below the top rim. Each catch is composed of a sprintongue y, attached at one end to the wa l of the part a on the insideand rovided with a short bolt or spur y on the ee end. This last-namedpart sits through an a er ture in the shell a at proper distance be owthe shoulder b, so that the catch will engage the notch 2 in the neckwhen the shell being pressed down into the bottle comes to a seat on thetop rim of the neck. As these fastenings are not accessible from theoutside after the device is inserted and fixed in the bottle, it can beremoved only by destroying either the device itself or breakin thebottle.

A wire-gauze strainer X is sometimes fixed in the chamber a below theguard m to exclude dust and insects.

. opening, and a Having thus described my invention, what I claim, anddesire to secure by Letters Patent, is

1. In a device for preventing refilling of a bottle, a shell having acylindrical body portion to fit into the neck of the bottle and a headof greater diameter than the mouth of the bottle to rest on and cover itand provided with an opening in the bottom of the body ortion, avalve-seat around said opening, a liinged upwardly-o ening valve havinga cupshaped body and a ange to fit the valve-seat, the top of the shellbeing rovided with an outlet-opening, and means or fixing the shell inthe neck of the bottle.

.2. The combination withabottle,'of a shell fixed in the neck thereofhaving an enlarged top adapted to seat on the rim and close the mouth ofthe bottle and a body ortion extending into the assage throug the neckand provided Wit an opening in the lower end, a valve-seat around saidopening, a hinged valve seated thereon and opening upwardly therefrom,the shell having an opening in the top and a standing rim around saiduard fixed Within the shell between the sai opening and the valve.

In testimony whereof I have hereunto set my name to this specificationin the presence of two subscribing witnesses.
